ROBERT L. BOYD, OF PLAINFIELD, NEW JERSEY.

PRINTING DEVICE.

Specification of Letters Patent.

Patented Sept. 3, 1912.

Application filed December 7, 1911. Serial No. 664,460.

To all whom it may concern:

Be it known that I, ROBERT L. Born, a citizen of the United States, andresident of Plainfield, in the county of Union and State of New Jersey,have invented certain new and useful Improvements in Printing Devices,of which the following is a specification.

This invention relates to the printing of photographs in ordinaryprinting frames, in which they are exposed to the light. In making suchprints from certain kinds of pictures, particularly such as show anexpanse of water, the camera, especially if held in the hand, willusually have the picture upon the exposed plate in an inclined position,that is, a horizontal line in the View, which should produce ahorizontal line in the picture, will be tilted or inclined from. thehorizontal.

The principal object of this invention is to provide means forcorrecting this defect or inaccuracy in photographs.

A further object of the invention is to provide means for shortening orenlarging at will either the foreground or the background of the pictureshown in the print.

In practising the invention I provide movable guards or screens aroundthe edges of the negative or film from which the print is being made,and these screens may be adjusted so as to bring the edges of the printinto the proper relation with the horizontal and vertical lines in thephotograph, or to modify the foreground or background.

The invention consists in the construction and combination of parts tobe more fully described hereinafter, and particularly set forth in theclaims.

In the drawing which fully illustrates my invention. Figure 1 is a frontelevation of the device as applied to an ordinary printing frame, theforward plate which lies adjacent to the glass of the printing framebeing represented as broken away, leaving merely the corners thereof inplace. This form of the device is particularly adapted to printing fromfilms. Fig. 2 is a front elevation of the device illustrating the mannerin which the screens cooperate to form a mask, the opening through whichis properly alined with respect to the horizontal and vertical lines ofthe picture. Fig. 3 is a longitudinal vertical section taken on the line33 of Fig. 1 and passing through an ordinary printing frame in erablyaluminum.

which the device is used. Fig. 4 is a front elevation showing a modifiedform of the device in which the screens may be adjusted to vary the sizeof the opening, but not permitting of any angular adjustment. This viewshows the side of the device which is adjacent to the glass of theprinting frame. Fig. 5 is the rear elevation of the device with a matsuperposed thereupon and forming a plate carrier. This form of thedevice illustrated in Figs. 4 and 5 is adapted particularly for printingfrom plates, that is, negatives formed on glass. Fig. 6 is alongitudinal section taken through Fig. 4 about on the line 66 and alsopassing through a photographic printing frame in which the device isheld.

Before proceeding to a detailed description of the device it mayexpedite the disclosure of the invention to state that the inventionpreferably is in the form of a supplementary frame or guard, which isplaced in the printing frame, lying against the glass. As the opening inthis supplementary frame is much smaller than the normal opening of theprinting frame, the printing frame is then adapted for printing picturesof a smaller size.

The preferred form of the device is intended especially for printingfrom films such as used in kodaks and similar cameras, although it maybe used with plates if desired. This form of the invention is disclosedin Figs. 1 to 3, inclusive, and will now be described. The device inthis form comprises forward plate 1 and a rear plate 2, which are of thesame size and of rectangular form, superposed upon each other and heldtogether at their corners by rivets or eyelets 3. These two plates haveopenings which register together to form a rectan gular printing opening4, as indicated in Fig. 2. The edges of this opening 4 are parallel withthe edges of the supplementary frame 5 which the two superposed platesform. In the space between the two plates 1 and 2 I provide four linksor arms 6, which are attached at the points indicated by pivots oreyelets 7, to the rear plate 2, that is, the plate which is not heldadjacent to the glass when the device is in the printing frame.Pivotally attached to the free ends of these arms 6 I provide guards orscreens 8, which are preferably in the form of thin, flat strips ofplate metal, pref- These screens have straight inner edges, and are ofconsiderable width as indicated. The pivot connections, or eyelets 9,which attach the screens to the arms 6 are preferably located near themiddle points of the screens. The ends of the screens overlap eachother, as indicated, and the screens are intended to be adjusted outinto the opening 4 so that the inner edges of the screens intercept thelight which normally passes adjacent to the edges of the opemng 4; inthis way the screens form an adjustable mask, and produce a smaller orsupplementary opening 10 within the opening 4.

It should be understood that in practice the plate 1 of the device liesagainst the glass 11 of the printing frame 12, as indicated in Fig. 3,and in order to facilitate the adjustment of the screens withoutremoving the mat from the frame, the inner edges of the upper or rearplate 2 are provided with are shaped slots 13, which are struck uponradii having their centers at the eyelets or pivots 7. Into these slotsthe eyelets 9 project and these projecting eyelets facilitate theoutward or inward adjustment of the arms 6. In this way, and by touchingthe fingers to the projecting edges of the screens the location andangular position of the screens can be adjusted.

The manner of adjusting the mask formed by the screens 8 to bring theedges of the opening 10 into proper alinement is illustrated in Fig. 2.The line 14 represents a horizontal line such as a horizon at sea, or asimilar line on the picture which is known to be horizontal. The upperand lower screens should. be swung out and adjusted on pivots 9, untilthey appear to be substantially parallel with this line 14, and then theend screens are adjusted so as to place them substantially at rightangles to the line 14. By adjusting the side screens in or out evidentlythe amount of foreground or background in a picture may be increased ordecreased as desired.

In Fig. 3, the film 15 is laid upon the glass 11, and back of the filmlies the print or sensitized sheet 16. Back of the print 16 I provide athick compressible pad 17 of felt, or other similar material, adapted toform a good cushion which accommodates itself to the inequalities ordifierences in thickness of the parts of the device in the vicinity ofthe supplementary opening 10. This pad insures that a substantiallyuniform pressure will be exerted by the back 18 when it is locked inplace. When it is not necessary to use the screens, that is, in makingprints from negatives not having the defects suggested, the screens maybe pushed back so that they recede completely into the space between theforward plate 1 and the rear plate 2. In order to accomplish this it maybe necessary to provide the outer edges of the screens 8 with notches19, as indicated in Fig. 1 which give clearness for the eyelet pivots 7The modified form of the invention illustrated in Figs. 4 to 6 will nowbe described. In this form the device consists of a plate 20 ofrectangular form which is provided with a rectangular opening 21, theedges of which are respectively parallel with the edges of the plate 20.On two adjacent edges of the plate 20 I attach fixed screens 22 whichare in the form of very thin metal plates preferably of aluminum, andthese plates are preferably secured by rivets or eyelets 23, as shown.Opposite the screens 22 I provide movable screens 24, which are alsoformed of thin plates. These screens 24 are mounted to swing in or outon parallel arms 25 which are pivotally attached by eyelets 26 to thescreens 24, and pivotally attached to the plate 20 by eyelets 27 inother words, the two screens 24 have a parallel movement. The edges ofthe two screens 22 are at right angles to each other and the edges ofthe screens 24 are parallel respec tively with the edges of the screens22. In this way a smaller and supplementary opening may be formed in theopening 21 of the plate 20.

In printing from plate negatives I preferably employ a mat or platecarrier 29 which is also of rectangular form and of the same dimensionsas the plate 20. This mat has a rectangular opening 80 which matches andregisters with the opening 21 when the mat 29 and plate 20 aresuperposed. This mat 29 is preferably of substantially the samethickness as the printing plate or negative 81 which it is intended tohold.

In using the device the plate 20 is laid upon the glass 32 of the frame33, that is, the face of the device shown in Fig. 4 lies adjacent to theglass. The mat 29 is then laid upon the plate 20 as illustrated in Fig.5, and the edges of the screens 24 are adjusted in or out so as to givemore foreground or background, or so as to change the length of thepicture as may be desired.

The corners of the opening 30 in the mat 29 are provided with smallclips or shelves 34 which receive the corners of the negative 31 andsupport it in the mat. In this connection it should be understood thatthe opening 30 is of just sufficient size to receive the negative. Thismat keeps the negative in place and insures that the edges of the printwill be parallel with the edges of the negative. When the negative is inthe mat its upper face, as illustrated in Fig. 6, should be flush withthe upper face of the mat, so as to equalize the pressure on the glass32 when the back 35 of the printing frame is placed in position over theprint 31 In Fig. 4 the edges of the fixed screens 22 are represented asprojecting beyond the adjacent edges of the opening 21. This arrangementproduces a small margin around the edge of the print, but if no marginis desired the inner edges of the fixed screens 22 may be made to alineexactly with the edges of the opening 21. This will form no margin onthe print and the fixed screens will then operate principally asreinforcements for the adjacent edges of the opening.

The body of the device in both forms is preferably constructed of cardboard, or similar material.
